Luxembourg SPF | Structures, Strategies & Private Wealth Management Guide

Key Fact: Private wealth management covers more than investment selection. It can involve asset ownership, investment management, succession, family governance and tax coordination. Luxembourg’s SPF is one specialised structure for holding and managing eligible private financial assets. 

Introduction

Managing private wealth becomes more complicated when investments, businesses and family assets are spread across different entities or countries. At that point, choosing where assets sit can matter just as much as deciding how they are invested.

Private wealth management brings these pieces together. It can cover investment decisions, ownership structures, succession planning and the administration of family assets.

Luxembourg is one jurisdiction used for this type of planning. Its Société de gestion de patrimoine familial, commonly called an SPF, is designed specifically for private wealth involving qualifying financial assets rather than commercial operations. 

What Does Private Wealth Management Include?

Private wealth management can cover several areas at once:

• Wealth preservation
• Investment management
• Asset ownership and structuring
• Family governance
• Succession planning
• Estate planning
• Risk management
• Tax and regulatory coordination
• Intergenerational wealth transfer

The important distinction is between managing wealth and structuring it. Investment management focuses on how capital is invested. Wealth structuring looks at how those assets are owned, governed and eventually transferred.

Why does this distinction matter?

A family may have a portfolio manager handling investments while a separate company, trust or foundation provides the ownership and succession framework. The two functions can work together without being the same thing.

Why Do Individuals and Families Need a Private Wealth Management Structure?

Wealth structures become more useful as the number of assets, family members or jurisdictions involved increases.

Common situations include:

• Investments held in several countries
• Family-owned businesses
• Multiple investment accounts
• Different generations with separate financial objectives
• Assets requiring centralised administration
• Cross-border ownership
• Long-term succession planning

The purpose is not simply to create another company. A suitable structure can give the family a clearer framework for ownership and administration while making future changes easier to manage.

What Are the Common Private Wealth Management Structures?

These structures serve different purposes. A vehicle designed for passive wealth holding may not be suitable for an operating business, while a foundation or trust may be more appropriate where succession or governance is the central concern.

What Is a Luxembourg Private Wealth Management Company (SPF)?

A Luxembourg SPF, or Société de gestion de patrimoine familial, is a specialised company created under Luxembourg’s SPF legislation.

Its exclusive purpose is the acquisition, holding, management and realisation of financial assets. Commercial activities fall outside its permitted scope. The SPF can take certain Luxembourg corporate forms, including a société à responsabilité limitée, société anonyme, société en commandite par actions and certain cooperative structures organised as an SA. 

What makes an SPF different?

• It is designed for private wealth management.
• Its activities are centred on financial assets.
• Commercial operations are excluded.
• Its participation in another company must not involve interfering in that company’s management.
• It cannot grant interest-bearing loans, including to companies in which it holds participations. 

This makes the SPF a specialised wealth vehicle rather than a general-purpose company.

Who Can Use a Luxembourg SPF?

An SPF is intended for private wealth management and is designed around individuals acting in the management of their private wealth. 

It can therefore be relevant where the underlying objective is to organise privately held financial investments through a dedicated Luxembourg vehicle.

Before using one, however, the proposed assets and activities should be checked against the SPF framework.

An SPF may be considered for:

• Individuals managing investment wealth
• Families holding financial investments
• Private investors seeking a centralised ownership vehicle
• Family structures with qualifying financial assets

It should not be treated as a substitute for a commercial company where the intended activity falls outside its permitted scope.

What Assets Can a Luxembourg SPF Hold?

The SPF framework is centred on financial assets.  These can include:

• Shares and other securities
• Bonds
• Cash and deposits
• Financial investments
• Participations in companies

An SPF cannot directly acquire real estate. Since 1 July 2021, restrictions also apply to holding real estate through certain Luxembourg or foreign partnerships and FCP structures. However, the SPF can hold real estate indirectly through capital companies. Real estate therefore requires particular analysis before being included in an SPF structure.

What is the key limitation?

The structure is built around financial assets. The nature of the asset should therefore be examined before transferring it into an SPF.

What Can a Luxembourg SPF Not Do?

An SPF is deliberately limited in scope.

It cannot:

• Conduct commercial activities
• Operate an ordinary trading business
• Interfere in the management of companies in which it holds participations
• Grant interest-bearing loans, including to companies in which it holds participations

It can, however, make certain ancillary advances or provide guarantees without charge in specific circumstances permitted by the framework. 

This distinction is useful when deciding whether the structure fits the intended wealth strategy.

How Does Private Wealth Structuring Work Through an SPF?

A straightforward structure can look like this:

Individual or eligible shareholder → Luxembourg SPF → Qualifying financial assets

The SPF becomes the dedicated vehicle through which eligible investments are held and administered.

This can help centralise ownership where a family’s financial assets would otherwise sit across several individual accounts or entities. The SPF itself does not replace wider succession, estate or tax planning; those matters can sit around the vehicle as part of the broader wealth strategy.

What Are the Main Benefits of a Luxembourg SPF?

The SPF’s value comes from its defined purpose rather than from being a universal tax or asset-protection solution.

Is an SPF tax-free?

No. The SPF has its own tax regime and is subject to subscription tax. Luxembourg increased the minimum annual subscription tax from EUR 100 to EUR 1,000 from 2025. 

The tax position of the SPF and its owners should therefore be reviewed based on the relevant jurisdictions and circumstances.

How Is a Private Wealth Management Company Different From a Holding Company?

The distinction matters because an SPF is intentionally passive in important respects. A structure expected to participate actively in the management or financing of operating businesses may require a different vehicle.

How Do You Set Up a Luxembourg Private Wealth Management Company?

The setup should start with the assets and the purpose of the structure rather than with incorporation paperwork.

The SPF framework permits several Luxembourg corporate forms, so the choice of legal form should be made alongside the wider ownership and administration plan. 

What Ongoing Responsibilities Does a Private Wealth Management Structure Have?

Once established, the vehicle needs to remain within its permitted framework.

Key responsibilities include:

• Corporate administration
• Accounting and financial records
• Subscription-tax compliance
• Annual corporate requirements
• Maintaining ownership and asset records
• Monitoring SPF eligibility
• Updating shareholder information where required
• Keeping supporting documentation current

The structure should be reviewed whenever there is a material change in its assets, ownership or intended activities.

When Should You Consider a Different Wealth Structure?

An SPF may not be the right answer where the underlying objective goes beyond passive private wealth management.

Consider whether another structure is needed when the plan involves:

• Operating a commercial business
• Actively managing subsidiaries
• Holding assets outside the SPF’s permitted scope
• Complex succession arrangements
• Philanthropic objectives
• A broader family-office function
• Collective investment involving multiple investors

In such cases, a holding company, family office, trust, foundation or investment fund may be considered instead ofor alongsidethe SPF.

What Should You Consider Before Choosing a Private Wealth Structure?

Before selecting a vehicle, work through the fundamentals:

• What assets are being structured?
• Who owns them today?
• Who should ultimately benefit?
• Is the priority preservation, investment, succession or all three?
• Is an operating business involved?
• How many jurisdictions are involved?
• How much administration is acceptable?
• What should happen to the assets across generations?

FAQs

What is private wealth management?

Private wealth management is a broader approach to managing personal or family wealth. It can include investments, asset ownership, succession, estate planning, risk management and tax coordination.

What is a private wealth management company?

It is a dedicated structure used to hold and organise eligible private assets. The exact form and permitted activities depend on the jurisdiction and the purpose of the vehicle.

What is a Luxembourg SPF?

A Luxembourg SPF is a specialised private wealth company whose exclusive purpose is the acquisition, holding, management and realisation of financial assets, while commercial activities are excluded. 

Who can set up a Luxembourg SPF?

The SPF framework is intended for individuals acting in the management of their private wealth, subject to the applicable ownership and eligibility requirements. 

Can an SPF conduct commercial activities?

No. Commercial activity is excluded from the SPF’s permitted purpose. The vehicle is designed specifically for private financial wealth management. 

Is a Luxembourg SPF suitable for family wealth management?

It can be, particularly where the objective is to organise qualifying financial assets through a dedicated vehicle. Suitability depends on the family’s assets, ownership arrangements, tax position and wider succession objectives.

What is the difference between an SPF and a Luxembourg holding company?

An SPF is designed specifically for private wealth management and has restrictions on commercial activity and active management of participations. A conventional holding structure can have a different purpose and may be better suited to corporate ownership or active group structuring.

Conclusion

Private wealth management is not limited to selecting investments. Ownership, administration, succession and long-term family objectives can be just as important when wealth becomes more complex.

A Luxembourg SPF offers a specialised vehicle for eligible private financial assets, but its restrictions also determine when it is and is not the right choice. The decision should begin with the assets, ownership structure and long-term objective rather than the name of the vehicle.

Arnifi can help coordinate the establishment and administration of a suitable Luxembourg private wealth structure, including SPF setup where appropriate.
